Rewrite it to simplify using order of operations.
P E M D A S
() ^2 × ÷ + -
So nw it's
5-1-(9÷3)-9
no now it's
(5-1)-(3-9)
4-(-6) I wrote the negative in parentheses to show its not an additional subtraction sign. also if you look it's sort of a plus sign. so when you subtraction (-6) from 4 it's actually 4+6
4-(-6)=10.
that's what I got. hope this helps.

Answer:
Step-by-step explanation:
The hour hand is 20 mm and the minute hand is
- 200% of 20 mm = 2*20 mm = 40 mm long
The tip of the hour hand travels 1/12 of the circle and the tip of the minute hand travels full circle in one hour.
Find each length and their difference using circumference formula.
<u>Hour hand</u>
- 1/12*(2*3.14*20) = 10.47 mm (rounded)
<u>Minute hand</u>
<u>The difference between the two above</u>
- 251.2 - 10.47 = 240.73 mm
